8.18. The association of accelerated early growth, timing of puberty, and metabolic consequences in children

YH Jee , S Jumani , V Mericq

Brief Summary: The mechanism by which suboptimal intrauterine growth and low birth weight for gestational age may lead to postnatal metabolic risks has not been well established. This narrative review summarizes recent studies on the association between early infant growth, timing of puberty, and metabolic risks, thus expanding our knowledge of the underlying pathophysiology.Comment: Early compensatory infantile growth in children born small for gestatio...

Brief Summary: this large patient cohort study identified an overrepresentation of functionally damaging variants in MC3R in individuals with constitutional delay of growth and puberty but not in patients with IHH.Melanocortin 3 receptor (MC3R) is a permissive signal expressed by hypothalamic kisspeptin-neurokinin B-dynorphin (KNDY) neurons. It activates puberty through the leptin-proopiomelanocortin pathway in response to nutritional signaling<...

Lancet Diabetes Endocrinol. 2020;8:594–605. doi: 10.1016/S2213-8587(20)30153-4.Groenenweg et al. present the so far largest retrospective multicentre cohort study on 151 patients with 73 different MCT8 (SLC16A2) mutations to compare and describe in detail the phenotypic spectrum and the disease course of MCT8 deficiency. The careful description of presenting cl...
